How about based on link maturity? A fresh link (under 20 days, e.g.) has nofollow to prevent spam links being added, those links which have survived many eyes over 20 days have nofollow removed.
Last time I did a big scrub I found plenty of overt nastyness (direct links to trojans, browser crashing popup spam sites, etc) that were in articles for long spans of time.
My working theory was that established heavy duty users don't follow external links too often since they take them away from the site, and the casual users don't know or care enough to remove bad ones. True or not, externals very clearly get little oversight on EnWP.
First there needs to come some level of recorded review/oversight. Simply trusting that the links will get seen as is done today is demonstrably highly failure prone. Once that exists, teaching nofollow to follow it is 'just' technical details.
